Likecoin – coins for likes: https://likecoin.pro/@demalit/pcg8/yeb9 ▬▬▬ ✉ Telegram channel: https://t.me/+BIOQ_ig6nOw3OWUy ▬▬▬ I plan to use a step-down digital voltage stabilizer or converter (DC-DC converter) to assemble a laboratory power supply. I traditionally ordered it in China, since everything is much cheaper there today, through the Aliexpress website. At the time of ordering, the DC-DC converter cost 9.50 USD. Delivery of goods from China was free. Fortunately, the tracking number was tracked. A 30-watt voltage stabilizer arrived in Minsk (Belarus) in 21 days. The quality of execution is excellent. As far as one can see, the soldering is very neat and quite reliable. There was no unpleasant smell from the board. The seller packed the step-down voltage converter in an antistatic bag, which he wrapped in a couple of rolls of bubble wrap. He placed all this in the shipping package. The dimensions of the digital stabilizer or voltage converter are as follows (length/width/height): 74.3 mm/43.1 mm/12.5 mm. The weight of the device is approximately 20 grams. The DC-DC converter is equipped with a voltmeter and ammeter. The indicators are 7-segment 4-digit. The DC-DC converter turned out to be fully functional! The output voltage has digital adjustment from 0 to 30 volts with an input voltage of 5 to 32 volts. The maximum output current of the voltage converter is 5 amperes. The voltage is adjusted in 0.1 Volt increments, and the current is adjusted in 0.01 Ampere increments. If the output current is over 1.5 Amperes, I recommend hanging the controller on a radiator for cooling. The blue LED indicator on the right indicates that the voltage stabilizer is on. Red LEDs indicate which voltage (input or output) is indicated on the built-in voltmeter. When the input voltage changes, the output voltage does not change. The voltage converter has a built-in preset memory. Since this is a step-down converter, the input voltage of the device must be one volt higher than the output voltage. I can safely recommend this digital stabilizer or voltage converter (DC-DC converter) for purchase!
